Portable Wireless Keyboard, Ultra-Slim 2.4Ghz Wireless Touchpad Keyboard All-in-One Wireless Keyboard with Sensitive Touchpad for Android Smart TV Google Box Raspbeeey HTPC IPTV Windows 10

the size is very convenient, but the touch pad works 90% of the time.

I tried to use this product on my 3 different smart Samsung TVs and it never worked for any of them.The red light comes on but that is it.
